Do not commence any conversation by the suggestion of painful or disagreeable topics. To ask a friend abruptly, "For whom are you in mourning?" may be tearing open anew a wound that was covered for the time by intercourse with society. Take other steps to satisfy yourself on this point. By the same token, do not say to a man, "That was an unfortunate affair, that failure of yours." Never, directly or indirectly, rub a sore. Do not ask questions which relate to the private affairs of the person spoken to, and be guarded against conduct which may look like an attempt to force confidence. If too persevering in your inquiries you may be treated, and very properly, as one might treat a highwayman who sought to rob one of any other property. A man's thoughts are certainly his own most private possession, and you must be very intimate to seek to be admitted to a share in them. Even if you are so, it is far more delicate to wait until confidence is offered to you. A man has a perfect right to defend himself from cross-examination by any means, except positive falsehood. In conversing with foreigners do not disparage any of their national customs, even if they are rude enough to attack yours. You may, pleasantly and frankly, defend the institutions of your native land, but not by comparison with the customs of other countries. If your companion is well-bred, he will admit that you possibly understand American customs better than a foreigner can do; if he is a low-bred man, no rudeness on your part will correct his manners or views. Subjects or incidents calculated to disgust the hearers, are to be avoided in polite conversation. There is a positive fascination to some people in describing sickening or revolting scenes, but well- bred people will remember that some are sensitive upon such subjects, and all would prefer more agreeable topics. Do not use surnames alone, even if speaking of intimate friends. For a lady to speak of her husband as "Smith" or "Jones," is vulgar in the extreme, and it is low-bred also to say "my husband," "my wife" or, except amongst relatives, to use the Christian name only, in speaking of husband or wife. Speak of your own husband or wife as, "Mr." or "Mrs. B---," and of your friends also by the surname prefix as, "Remember me to Mr. or Mrs. D." Let no more than one person be speaking at one time. Ridicule and personal joking cannot be too severely censured. Avoid an officious offer of advice or your own opinion, and if you do give an opinion, be sure it is given as such and not as a fact. If you would preserve a character for truthfulness, avoid the too common fault of exaggeration. When visiting, be careful that you do not appear to undervalue anything around you by comparing it with what you have at home. Beware of personal abuse or invective. Remember what Shakespeare put into the month of Cardinal Wolsey, when the Earl of Surrey said to him on his disgrace:
